I just changed the
oil for the first time since I purchased my SPF. I do not know what brand or viscosity of
oil was in the car when I purchased it but I put in Lucas full
synthetic racing 20W 50 (20W 50 is recommended by the engine manufacturer). I installed a Motorcraft FL1-HP filter. After the initial start up, I noticed a different smell coming from the engine bay and/or exhaust. It is not electrical and I made sure there were no leaks. Is it common for different motor oils to produce different odors?
Also, I noticed my
oil pressure increased about 7-8 psi at idle and when I increased the RPM's compared to pre-oil change. I did not get a chance to drive the car so I do not know what the pressure is under driving conditions. Is higher pressure a characteristic of full
synthetic oils?
